CARBU-RETER FOR STATIONARY ENGINES AND OTHER PURPOSES.

Specification of Letters Patent.

Application filed February 211i, 1910, Serial No. 545,773. RenewedJanuary 15, 1913. Serial No. 742,310.

To all whom t may concern:

Be it known that l, CHARLES H. MYERS, a citizen of the United' States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful.

izing hydrocarbons for use in the explosive g chamber of stationarycombustion engines, and consists in certain novel features ofconstruction and arrangement ot parts which are illustrated in theaccompanying 'drawings and will be hereinafter' fully described and thenpointed out in the claims.

In the accompanying drawings, Figure 1 is a central verticallongitudinal section of a carbureter embodying my invention. Fig. 2 isan end elevation of the same partly broken away. Fig. Sis a view partlyin horizontal section and partly in plan of my device. Fig. 4 is atransverse vertical section. Fig. 5 is a detail View hf one ot' thepartitions. Fig. 6 is a detail section of the throttle valve arranged inthe outlet.

ln carrying out my invention, ll employ a housing or casing l which maybe of any desired size-and form and which is provided at one end with anair inlet 2 over which is placed a screen, as clearlyshown in Figs. 1and 2. Over this air inlet l secure a dome or semi-spherical hood 3 fromwhich rises an air inlet pipe 4 provided at its irpperend with acup-shaped enlargement 5 provided with a transverse bar 6- at its openupper' end in which is lmounted a threaded shaft or `screw 7 carrying ahand wheel 8.' By turning this hand Wheel, the screw 7 will be causedtovmove through the bar 6 and thereby bring the hand wheel closer to orfarther from the open end of the cup 5 and thereby control the inlet ofair to the carbureter. This adjustment is eli'ected at the factory andis determined by the size ot' the carbureter and the capacity of theengine to which it is to be fitted and the adjustment is notsubsequently changed. ln the upper side of the housing 1, at theendopposite the air inlet, l provide a screened outlet 9 through which thevapor-laden air may pass so as to escape through the pipe 10 to theengine. This pipe 10 leads from a dome 11 which is secured over theoutlet opening 9 and the opposite end of the pipe 10 is secured to orformed integral With a valve casing 12 in which is mounted ahandcperated valve 13 adapted to cut oli' the outletent-irely or to varythe amount of vapor permitted to escape by being moved more or less fromits'seat, as will be readily understood. lllhe seat for this valve 13 isformed on one side of a dome or cup 14 within which l provide one ormore screens lo and from which a pipe 16 leads to the en- Within thehousing 1, l provide a plurality of superposed compartments orcontainers 17 and in each of the said compartments or'containers, lprovide an absorbent oil holder 18 which is preferably lamp wicking cutinto proper lengths and set on end within the compartments soA that thecapillary passages will be vertically disposed. rlhe wicking is held inthe compartments by a series of rods 19 disposed transversely thereinbelow the mpper edges of the same, whereby oil ted tothe uppermostcompartment will be permitted to 'overflow therefrom after saturatingthe absorbent material and pass into the next lower compartment, wherethe same action will occur, whereby the several compartments will`besuccessively supplied with the oil.

ln the form of the invention illustrated in the drawings, the severalcompartments are provided by a seriesof pans disposed l0ngitudinallywithin the housing and arranged in staggered relation, as will be mostreadily understood on reference to Fig. 1l. The lowermost compartmentwill lill the entire bottom of the housing, while the next superposedcompartments will have their longitudinal edges in Contact with eachother and with the sides Vof the housing, thereby leaving spaces 20between the sides of the housing and the compartments and between thecompartments,'as clearly shown in Fig. 4, so as to permit a large volumeof air to pass over the lower compartment, as will be readilyunderstood. rlhe third horizontal row of compartments will be sodisposed that the spaces between the same will be arranged over thesubjacent compartments, as clearly shown in Fig. 4 and, consequently,air passing through the said openings will be compelled to travel overthe lower compartment, and the saturated absorbent ma` terial therein.The oil is admitted to the uppermost compartments through a valve 21Patentes aug. raisers.

connecting a feed cup 22'with the top of the housing and will pass fromthe said valve dito further provide for `an even distribution rectlyonto the absorbent material in the uppermost compartments. From thesecom partments, the oil will overflow through openings 23 in one end ofthe same into the next subjacent compartments and will overtlow lfromthe said compartments through openings 24 at the opposite end thereof,and so on to the lowest compartments. In order and aid in supporting thesuperposed compartments. They also permit the surplus oil .to spreadevenly through the absorbent material and to pass readily from onecompartment to the next lower compartment. This spacing of thepartitions, furthermore, serves to divide the air current passing overthe absorbent material and, consequently,

bring the said air current into intimate contact with the entire surfaceof the absorbent material, so that the oil held by the said materialwill be thoroughly vaporized and taken up by the air and a richhydrocarbon gas supplied to the engine.

It will be understood, of course, -that the device may be made of anydesired capacity and is charged with the hydrocarbon oil at suchintervals as may be necessary by having the said hydrocarbon simplypoured through the cup 22 and the valve 21 connected therewith. A stopcock 27 is pro- 'vided at one end of the housing immediately above theupper surface of the absorbent material in the lowest compartment, andthis stop cock is opened when the device is to be charged. Thehydrocarbon Howing into andV from the several compartments willeventually reach the lowest compartment and will saturate the absorbentmaterial therein and will then tend to collect on the upper surface ofthe same.

This excessive oil will escape through the stop cock 27, and theoperator will at once close the said stop cock and also stop thecharging operation, the said stop cock serving primarily `as a means ofinforming the operator when the device has been fully charged. It mayalso be utilized as a drain, and will be found advantageous also whencleaning or repairing of the mechanism becomes necessary. While thepartitions 25 may be of any desired character consistent with theoperation of the invention, l prefer to construct them of corrugatedmetal plates in order that the ni'shed structure may have the strengthnecessary to withstand the vibrations caused by the engine and also toprevent being pulled apart under the severe draft or suction, the endsof the pans are secured directly to the endsof the housing, as shown at28, so that `the air entering through the inlet 2 will be directedvinitially upon the surface of the absorbent material in the lowestcompartment. The air current will then lpass to theop'posite end of thehousing and will rise to the overflow opening 241 and pass through thesame and then over the surface of the material in the compartmentcontaining the said opening, the ascent of the air directly through thehousing being prevented by the end of the next superposed compartment,as willbe readily understood on reference to Fig. 1.

The carbureter, herein disclosed, is charged with hydrocarbon or othervolatile fluid in the described manner, and the throttle valve 13 isadjusted according to the demands from the engine andthe conditionsunder which work is being performed. The en gine, having been set inmotion, will draw air through the carbureter, and this air will passover or through the several oil-containing compartments and willvaporize and take up the oil therein so that when the air current passesthrough .the outlet opening 9, it will be laden with a rich gas orhydrocarbon vapor and, consequently, will supply a highly charged gas tothe engine. The gas lthus supplied, will be further mixed with air atthe engine before passing into the combustion chamber of the same, andthis final air feed will be controlled by the engineer and regulatedaccording to the eXigencies of any particular occasion.

The domes or cup-shaped hoods which are secured over the air inlet andthe gas outlet openings provide an enlarged chamber over the saidopenings in which the. air or vapor may collect and, consequently, serveas a cushion to counteract the pulsations of the engine and prevent thesaid pulsations disturbing the conditions within the carbureter orcausing the oil to leak from the several compartments. The ends of thecompartments are inclined inward and downward from the ends of thehousing so as to provide spaces within which the air may circulate andpass'from one level to the next level above the same so as to pass overthe surfaces of the absorbent holders within all the compartments, andthe particular form of absorbent holder preferably used by me utilizesthe force of capillary attraction to bring' every drop of the volatilefluid to the surface to be acted upon by the air current.

4From the foregoing description, taken in connection with the,accompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together 4.with the apparatuswhich I now consider to be the best einlbodiment thereof, I desire tohave it understoodv that the apparatus shown is merely illustrative, andthat such changes may be made when desired as are within the scope ofthe claims appended hereto.

I-n my application No. 545,774, for carbureter for household and otheruses, filed Feb. 24, 1910, there are shown and described features uponwhich claims in this case are readable,lbut no claim is made in saidapplicatio-n broadly to such features which is readable upon thedisclosure of the present application.
